RlmM catalyzes the 2′-O-methylation at nucleotide C2498 in a single stranded part of the peptidyl transferase loop (between hairpins 89 and 90, Domain V) of E. coli 23S rRNA. Methylation occurs in naked 23S rRNA, but not in assembled 50S subunits or ribosomes. RlmM is placed in the cluster of orthologous groups COG2933 together with S-adenosylmethionine-dependent, Rossmann-fold methyltransferases (notably fibrillarin Nop1).
